Biodiversity, Evolution and Disease¶

Module 4 joins organism diversity, ecology, immunity and evolutionary change. These ideas connect naturally: pathogens drive selection, biodiversity is measured and conserved, and classification reflects evolutionary relationships.

Core Role¶

• Introduce pathogen types, transmission and immune responses.
• Define and measure biodiversity at habitat, species and genetic levels.
• Connect classification, phylogeny, variation and natural selection.

Learning Objective Map¶

Each Module 4 topic page now opens with a specification-aligned Learning Objectives section. Use these links to move between disease, biodiversity and evolution without losing the assessed topic boundaries.

Topic Pages¶

• 4.1.1 Communicable diseases, disease prevention and the immune system
• 4.2.1 Biodiversity
• 4.2.2 Classification and evolution
